Global foam concrete market trend 2023-2027 The solution to the collapse of foam concrete by Newshotel-cisar

The biggest immediate challenge for the EU will be replenishing its depleted gas inventories. While the EU could still increase LNG imports from countries such as the US, such purchases would be more expensive.
Refilling natural gas storage space to historical average levels this year could cost 70 billion euros, a sevenfold increase, compared to 10 billion euros in previous years. "
A complete replacement for Russian gas is not only very expensive, but it also may not be possible.
In the next 12 months, there is little way to meet the demand for a "normal" year in the absence of Gazprom, which also includes foam concrete.

The common problems of foamed concrete are bubbling, cracking, collapse, shrinkage, and other phenomena. To treat these phenomena, the proper medicine can be found, and the cause can be effectively solved.

The main reason for the collapse of foamed cement is that the cement solidification speed is too slow. We can solve this situation from the following aspects

1. Add accelerator to improve the setting time of foamed cement

Accelerators are used in more and more concrete applications. Foamed cement has high requirements for accelerators. It is not just a fast setting but also needs to be adapted to the performance of foamed cement, and accelerators cannot be added. After affecting the foaming situation.

2 Add an early strength agent to improve the early strength of foamed cement and reduce the stress generated during the exothermic process of cement hydration. Only when these two forces are balanced can it be ensured that the foamed cement will not crack and collapse in the later stage.


3. An appropriate amount of sulfoaluminate cement can be added, which many manufacturers choose to use in winter, and the cost performance is still relatively high. However, this amount of addition should also be paid attention to. It should not be added blindly. After many customers add sulfoaluminate cement, the finished product becomes very brittle in the later stage, without toughness, low strength, and severe pulverization. So we still have to adjust according to the current situation.

4 The water-cement ratio is not suitable. Collapse, retraction, bleeding, insufficient strength. To a large extent, it has something to do with the inappropriate water-cement balance. The adjustment of the water-cement ratio is a technical activity that requires trial and error. It has a lot to do with the cement of foamed cement and the fly ash aggregate, and it needs to be practiced repeatedly according to the actual situation. In this, we can add a plasticizer to adjust the water-cement ratio. This effect is very immediate.

The above contents are some solutions summed up by Tongrun according to the reasons for the collapse of foamed cement. If you encounter other problems or reasonable solutions in the actual process, you are also welcome to communicate us.

Recently, drone giant DJI said it would suspend operations in Russia and Ukraine to ensure its foam concrete are expected to continue to be influenced by international geopolitical situations.
